The guys — with drummer Michael Martinez — chatted about how life has changed for them and what really inspired their new single, “Blame It on September.”

Zach shared, “It was nothing too special. Just met a girl at a fair once and…well, it happens to everyone, I guess. We liked each other, we hung out and then at the end of summer, we went to different schools and she wanted to break up. So, it kind of sucked.”

“Things in life don’t always end up exactly how you first planned, hoped, or envisioned. More than anything, we wanted this band to work out with Nathan in it, but as our band progressed, he went on a different path both professionally and personally, and we mutually decided to part ways. We didn’t tell you until now because nothing was 100% definite until very recently. The details are between us and Nathan, and while we’re sure everyone will ask what happened (for the record, he is happy and healthy), it’s a personal matter that needs to stay within the band. Please respect both Nathan and us with this very difficult decision. Most importantly, this doesn’t change who we are, the music we play, the passion we put into this band, what we stand for, or our love for our fans.

“Eric filled in on guitar only for the summer, and now we will begin our search for a new, permanent member of Allstar Weekend.

“We have a new record coming out on September 27th called ‘All The Way’ that we put a ton of heart and soul into, and we can’t wait for you to get it. In January & February 2012, we will be headlining a full US tour with select dates in Canada in support of ‘All The Way.’ As always, we can’t wait to see and meet you.

“To all of our fans who stood by us during this difficult transitional period – we want you to know that we love you and thank you for your never-ending support. You are the reason we are here.
